and curved downwards. The leaf of the wild plant, now before 
me,, is S inches long and 4 wide, terminal spine very stout, 10-11 
lines long, decurrent about the same distance ; arrangement of 
marginal teeth quite peculiar, the uppermost ones the largest, 
ii-2^ lines long from a broader base,; straight, almost black and 
very rigid, 6-8 lines apart ; teeth, below the upper third smaller 
and closer set, and below the middle only 2-3 lines apart, less 
than r or only T line long and strongfy curved downwards. 
Scape 12 feet high, branches of the panicle loosely ramified, 
branchlets 3-6 inches long, pedicels 1-2 lines long ; flowers in 
small clusters, 3-6 or 8 together, 2A inches long, perigon half as 
long, divided to the middle; stamens inserted about I from the 
. base of tube, exsert about f inch above lobes; anthers io-iol 
lines long. Capsule 18-22 lines long, 7-8 wide, similar to that 
of last species but not stipitate; seeds 2f lines in diameter, cells 
-of the surface, under the microscope, flat, punctulate. 
I have a flower and a capsule of Agaves differing from any 
above described, and thus perhaps indicating two other species; 
but as the material is too incomplete to characterize them, I only 
indicate them here for further investigation. 
Agave sp. 44 Common on mountain-sides in the Wild Rose 
Pass on the Limpio,” West Texas, Chas. Wright, No. 1906 ; 
flowers only, collected June 11, 1851, referred by Torrey in Bot. 
Bound. 213 to A. Americana. Flower not quite 3 inches long, 
perigon equal to ovary, divided to the middle ; stamens inserted 
about i up the funnel-shaped tube, reaching 14 lines above the 
lobes; anthers 10 lines long.—Could it belong to the last de¬ 
scribed species, which was found 300 miles further south? 
Agave sp. Dragoon Mountains, Southeastern Arizona, Capt. 
Chas. Bendire, U. S. A. A capsule and seeds only, with the 
verbal information that the leaves are about 3 feet long and 4 
inches wide, and the scape nearly 20 feet high. The capsule is 
ovate-prismatic, 2 inches long, 10 lines wide, strongly cuspidate, 
at base obtuse; seeds 3! lines in longest diameter, apparently 
minutely pitted.—It is not probable that this could be a form of 
A. Americana, as that species has, I believe, always a stipitate 
capsule and larger seeds with flat, punctulate areas.
